FARM FIELD MANAGEMENT SYSTEM

To provide a farm field management system which allows a user to easily grasp the mid-drying condition of a farm field.SOLUTION: A farm field management system is provided, comprising a water supply device 11 for opening and closing a water hydrant for feeding water to a farm field H, an acquisition unit 16a for acquiring water management information including information on the degree of opening of the water hydrant, and an estimation unit 16b configured to estimate the mid-drying condition of the farm field H based on the water management information and time information on time associated with the water management information, where the estimation unit 16b estimates whether the water level of the farm field H is zero or not in the mid-drying condition estimation.SELECTED DRAWING: Figure 2 【課題】中干状態を容易に把握することが可能な圃場管理システムを提供する。【解決手段】圃場Ｈへの給水を行う給水栓を開閉する給水装置１１と、給水栓の開度に関する情報を含む水管理情報を取得する取得部１６ａと、水管理情報、及び水管理情報に紐付けられた時間に関する時間情報に基づいて、圃場Ｈの中干状態を推定する推定部１６ｂと、を具備し、推定部１６ｂは、中干状態の推定において、圃場Ｈの水位がゼロの状態であるか否かを推定する。【選択図】図２
